Title: Capteur aps a redondance et autoreparation integrees
Inventor: CHAPMAN GLENN HARRISON
IPC: H04N5/217
Filed: 2001-10-30
Abstract: Ce capteur APS (à pixel actif) répare lui-même des défaillances communes de dispositif. La zone de détection et le transistor d'affichage sont divisés en deux structures parallèles, de sorte que si le signal provenant d'une moitié est défaillant, la moitié de capteur APS restante peut encore produire un signal dont la sensibilité est cependant inférieure à celle de l'original. L'invention concerne également des procédés d'étalonnage servant à identifier les pixels possédant ces problèmes. Les informations provenant des pixels défaillants peuvent être corrigées par du matériel ou un logiciel, aux fins de production d'un pixel possédant une résolution numérique légèrement inférieure (une précision inférieure à un bit) à celle de dispositifs fonctionnant totalement. Il est possible d'améliorer encore la fiabilité en séparant les transistors de remise à zéro de chaque diode. Des algorithmes de logiciel sont mis au point qui améliorent grandement la récupération du signal au niveau des emplacements des pixels défaillants, même dans des conditions de défaillance importante, un algorithme de logiciel destiné à récupérer les pixels couleur défaillants étant notamment mis au point.

Inventor: FOX DAVID A
IPC: H02P9/10
Filed: 1989-12-11
Abstract: ABSTRACT OF THE DISCLOSURE A qenerator voltage regulator circuit is provided with a switching circuit for alternatively connecting or disconnecting a generator exciter field winding to a DC power source.  A discharge circuit is provided for conduct-ing current, produced by a collapsing magnetic field in the exciter winding following disconnection of the winding by the switching circuit, in a reverse direction through the DC power source.  A driving circuit controls the switching circuit with a series of turn-on pulses.  Each  of  the turn-on pulses is initiated in response to a transition in a clock signal and is terminated alternatively when the current in the exciter field winding reaches a predeter-mined magnitude or when a second transition occurs in the clock signal.  This invention also encompasses a method of regulating exciter field current performed by this circuit.

Patent CA-2008648-A1 (CA)
IPC: H04L12/56
Filed: 1990-01-26
Abstract: The invention provides a method for transmitting, via a transmission medium with a plurality of virtual, asynchronously time-divided transmission channels, a flow of data, and in particular a method for protecting these transmission channels against an exceeding of the maximum cell frequencies, based on the "leaky bucket"-entrance monitoring method. According to the invention the state of the counter of the relevant channel will be decreased on the arrival of a data cell by a value which is a function of the length of time between the moment of arrival of that data cell and the moment of arrival of a preceding data cell with the same channel indication. The decrease of the state of the counter takes place under the same time regime as the arrival of the data cells. Also the increase of the state of the counter, the comparison of that state of the counter with a threshold value and the switching through or not, dependent on the result of the comparison, of the data cell takes place under the same time regime. Owing to this, the monitoring device can function synchronously with the successively arriving data cells in a completely time-divided way, due to which all the virtual channels can be monitored individually by means of only one such a monitoring device. The value by which the state of the counter is decreased on the arrival of the data cell is preferably the product of a first constant value and said length of time between said two moments of arrival. The invention also comprises a device for carrying out said method and is for that purpose provided with read-out means (1), storage means (3, 5, 7, 9, 12, 14), time indicating means (4), computing means (6, 8, 10, 11, 15), means of comparison (13) and switching means (2).

Title: Dual action equalizing apparatus
Inventor: CETNAROWSKI ROBERT W
IPC: F01B9/04
Filed: 1990-03-19
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for providing a reciprocating motion.  The apparatus has a housing block that contains twin piston guides in spaced apart rela-tionship to one another.  The piston guides each contain a piston that has a gear rack.  The gear racks are connected by a pinion gear so that the move-ment of one piston will cause an equal and opposite movement of the other piston.  The movement of the pistons is controlled by the application of a fluid pressure to one or both of the pistons.  The travel of the pistons is limited by a mechanical stop at one end and a fluid cushion device at the other end.  Tools for the altering of a workpiece may be attached to one or both ends of the pistons.  In one embodiment  the apparatus is subjected to a rotary displacement achieved through the linear motion of one of the pistons.

Title: Method and means of conveyance of solid matter in pieces or particles
Inventor: JONKKA ARVO
IPC: B27L1/00
Filed: 1990-06-06
Abstract: Method and means of conveyance for solid material, f.ex. tree trunks (6) or bark, whereby the solid material is conveyed with parallel, oblong transfer elements (4) moving back and forth in transfer direction. A larger part of the surf ace of the transfer elements (4) is moving forward at a time than moving backward. The speed of the return motion of the transfer elements is higher than that of the feed motion of the trans-fer elements. Transfer elements (4) at sides of the conveyor have been inclined on their longi-tudinal axis so that they slope towards the centre of the conveyor. In this way the friction force between the particles (6) of the material to be conveyed is increased and the friction force between the maternal (6) to be conveyed and the transfer elements (4) is decreased.

Abstract: ABSTRACT OF THE INVENTION         The present invention relates generally to meth-ods of enhancing seismic data and, more particularly, to methods of attenuating noise in seismic signals.  The seismic data are sorted into gathers of seismic signals, and selected coherent events in each gather of seismic signals are aligned.  The gathers of seismic signals are then processed so as to transform the balance of the coherent events in each gather of seismic signals into incoherent events.  A two-dimensional filter is then applied to the transformed signals to attenuate incoherent events.

Title: Synthetic apparatus for inspection of blood
Inventor: KANAMORI SHIGEO
IPC: G01N33/483
Filed: 1990-09-05
Abstract: A blood analyzer system incorporates means for handling and transporting sample blood through at least one blood analyzer and an automatic blood smear generator under the control of a programmable controller. Blood samples are stored in sample containers having identifiers for the sample blood that they contain. These sample containers are transported through the system in protective racks that permit the reading of the identifiers. The results of analysis by one or more blood analyzers in the system determines the need for performing or omitting subsequent operations on a particular sample blood. When a smeared blood sample is to be made, the controller assures that the smear thickness is consistent with other samples regardless of the thickness or viscosity of the sample blood. If the system fails to make a required smeared blood sample, a detector sounds an alarm, warning of a system failure.
